Description

Technical Field

[0001] The present invention relates to the technical field of metallurgical construction, and in particular to a method for installing indoor track beams of a three-dimensional integrated pump station in a confined space. Background Art

[0002] In the metallurgical construction field, a common integrated pump house is typically arranged in a parallel configuration, with a water tank on one side and a pump station on the other. However, due to the limited site conditions, a side-by-side layout cannot meet the construction process requirements, so an up-and-down layout is required. One up-and-down layout has the water tank at the bottom and the pump station above it; the other is an elevated water tank, which is a three-dimensional integrated pump station with the water tank at the top of the pump station.

[0003] The main equipment in the pump station includes various pumps, valves, pressure tanks, and dosing devices. These devices are installed and maintained using indoor electric hoists, which are generally located below the indoor ceiling (the electric hoists are suspended below the I-beam track beam). The I-beam track beam is connected to the ceiling beam using bolts and connecting plates. Bolts pass through pre-reserved bolt holes in the reinforced concrete beam, are secured at both ends with steel connecting plates, and are bolted to the upper flange of the I-beam track beam at the bottom.

[0004] Conventional installation involves drilling a hole through the floor slab, then hoisting the track beam upwards using a wire rope (or fall chain). Scaffolding, a movable platform, or a lift is then set up, with construction workers standing above. The pool itself has high waterproofing requirements. When the pool is located on top of a pump station, the floor slab serves as the pool floor, making it impossible to drill a hole and effectively hoisting the track beam. Summary of the Invention

[0005] In order to solve the above problems in the prior art, the present invention provides a method for installing and constructing indoor track beams of a three-dimensional integrated pumping station in a confined space.

[0006] The present invention provides a method for installing and constructing indoor track beams of a three-dimensional integrated pumping station in a confined space, which adopts the following technical solutions: A method for installing indoor track beams of a three-dimensional integrated pumping station in a confined space comprises the following steps: S1. Making a connecting frame for connecting track beams; S2. Fix the lifting lugs on the top of the connecting frame; S3. Install the connecting frame on the concrete beam; S4. Hang a hand chain hoist on the lifting lug, and connect the hand chain hoist to the track beam through a wire rope or a lifting belt; S5. Lift and install the track beam at the bottom of the connecting frame; S6. Remove the hand hoist.

[0007] By adopting the above technical solution, this construction method avoids the traditional method of drilling holes from the top of the floor slab and using wire ropes and fall chains to lift the track beams. Instead, it uses the connecting frame as a support point, welds a lifting lug on its upper part, and hangs a hand hoist on the lifting lug to lift the track beams. It changes the operation from above the floor slab to operation from below the floor slab, avoiding the need for drilling holes in the floor slab and subsequent sealing, while avoiding the risk of water leakage due to inadequate sealing, and achieving the goals of cost reduction, efficiency improvement, and green construction.

[0008] Optionally, the connecting frame includes two connecting vertical plates, one of which is longer than the other, and the outer side of the connecting vertical plates is vertically fixed with a stiffening rib plate. The two connecting vertical plates are connected to the concrete beam by through bolts. The bottom ends of the two connecting vertical plates are fixed to a connecting base plate, and the connecting base plate is connected to the track beam by connecting bolts. The lifting lug is fixed to the top of the longer connecting vertical plate or the top of the stiffening rib plate located on the longer connecting vertical plate.

[0009] By adopting the above technical solution, the connecting frame structure is reasonably designed, the ear plates are easily fixed, and the overall structure has strong stability.

[0010] Optionally, a connecting middle plate is fixedly connected between the middle parts of the two connecting vertical plates, and the connecting middle plate is arranged against the bottom surface of the concrete beam.

[0011] By adopting the above technical solution, the stability of the overall structure of the connecting frame is further improved.

[0012] Optionally, the track beam is made of I-beam.

[0013] Optionally, determine whether the lifting lug affects the passage of the electric hoist located on the track beam or the overall aesthetics. If so, cut and remove the lifting lug; if not, retain the lifting lug. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following combination Figure 1 The present invention is described in further detail.

[0017] The embodiment of the present invention discloses a method for installing and constructing indoor track beams of a three-dimensional integrated pump station in a confined space. Figure 1The installation and construction method of indoor track beams of a three-dimensional integrated pumping station in a confined space includes the following contents: S1. Fabricate a connecting frame 4 for connecting the track beam 1. Specifically, the connecting frame 4 includes two vertically arranged connecting risers 40 for contacting the side of the concrete beam 3. One connecting riser 40 is longer than the other connecting riser 40, and a gap is left between the top of the longer connecting riser 40 and the bottom surface of the concrete floor slab 2. A connecting middle plate 41 is vertically welded between the middle portions of the two connecting risers 40. The connecting middle plate 41 is used to contact the bottom surface of the concrete beam 3. A connecting bottom plate 42 is welded between the bottom ends of the two connecting vertical plates 40, and a stiffening rib plate 43 is vertically welded on the side of each connecting vertical plate 40 facing away from the connecting middle plate 41. The stiffening rib plates 43 and the connecting vertical plates 40 are perpendicular to each other. The connecting vertical plates 40, the connecting middle plate 41, the connecting bottom plate 42 and the stiffening rib plates 43 constitute a connecting frame 4 for connecting the concrete beam 3 and the track beam 1.

[0018] S2 . Fixing the lifting lug 7 to the top of the connecting frame 4 , specifically comprising: welding and fixing the lifting lug 7 to the top of the longer connecting riser 40 or the top of the stiffening rib 43 on the longer connecting riser 40 .

[0019] S3. Installing the connecting frame 4 on the concrete beam 3 specifically includes: the construction personnel stand in a lifting vehicle, scaffolding or crane, buckle the connecting frame 4 on the concrete beam 3, and fix the connecting frame 4 by passing the through bolts 6 through the concrete beam 3 and the two connecting vertical plates 40.

[0020] S4, hanging the hand chain hoist 8 on the lifting lug 7, specifically including: hanging the hand chain hoist 8 on the lifting lug 7, using the lifting lug 7 as a hanging force point, and the hand chain hoist 8 uses a wire rope 9 or a sling to firmly bind the track beam 1.

[0021] S5. Lift and install the track beam 1 at the bottom of the connecting frame 4, specifically including: the track beam 1 is made of I-beam, and the construction workers manually pull the hand hoist 8 in the lifting vehicle, scaffolding or crane frame, and the wire rope 9 or sling pulls the track beam 1 slowly to lift it. When it is lifted to the installation elevation, the upper flange plate of the track beam 1 is connected to the connecting bottom plate 42 in the connecting frame 4 through the connecting bolts 5.

[0022] S6, dismantling the hand hoist 8, specifically including: after the track beam 1 is installed, removing the hand hoist 8 on the lifting lug 7. If the lifting lug 7 does not affect the passage of the electric hoist located on the track beam 1 or the overall aesthetics, it is optional not to cut and dismantle the lifting lug 7.

[0023] The indoor track beam installation and construction method of the three-dimensional integrated pump station in a confined space in an embodiment of the present invention avoids the traditional method of opening a hole from the top of the floor slab and using a wire rope in combination with a fall chain to lift the track beam. Instead, the connecting vertical plate 40 is used as a support point, and a lifting lug 7 is welded on the upper part thereof. A hand hoist 8 is hung on the lifting lug 7 to lift the track beam 1, and the operation from above the floor slab is converted to operation from below the floor slab, thereby avoiding the situation of opening a hole in the floor slab and subsequent sealing, and at the same time avoiding the risk of water leakage due to inadequate sealing, thereby achieving the purpose of reducing costs, increasing efficiency and green construction.

[0024] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
